Celeste is kicking off with a pair of pathfinder spacecraft, IOD-1 and IOD-2. IOD-1 (In-Orbit Demonstration 1) is the first in-flight testbed for the program’s low-Earth-orbit positioning, navigation, and timing approach, focusing on validating navigation payload concepts and end-to-end operations in space. The two pathfinders are intended to exercise complementary designs and operational approaches before the wider demonstrator constellation is deployed.

On March 28, the Celeste IOD-1 spacecraft, engineered by GMV and Alén Space for the European Space Agency (ESA), lifted off from Rocket Lab’s LC-1 facility in Māhia, New Zealand. At 10:14 CET, the pair of satellites—one from GMV and the other from Thales Alenia Space—reached orbit and separated from the vehicle roughly an hour after liftoff. Rocket Lab provided launch services and the LC-1 launch site for this mission; additional launch sites for later Celeste flights are not specified here. That milestone opened their commissioning phase, when mission control configures systems for sustained operations in space.

As an ESA-led in-orbit demonstrator, Celeste IOD-1 is intended to validate core LEO-PNT building blocks in flight, including the generation and broadcast of navigation signals, precise timekeeping and timing distribution, and the associated space-to-ground links and ground processing needed to assess signal and system behavior in orbit. It also supports tests of receiver and processing concepts for using LEO measurements together with existing GNSS observations, as well as monitoring approaches aimed at characterizing signal performance and operational stability over time. ESA’s role includes setting mission objectives and technical requirements, funding and program oversight, and coordinating technical validation and performance assessment across the industrial teams.

Augment Galileo and EGNOS. The demonstrator is structured so future user concepts can combine LEO measurements with Galileo ecosystem services and receiver processing. This supports evaluating interoperability considerations, integration pathways, and how a LEO layer could be used in conjunction with established service definitions.

Strengthen European satellite navigation. The mission contributes to European sovereignty by advancing an independently governed capability roadmap for navigation services and reducing reliance on non-European alternatives for critical PNT use cases. It also helps mature industrial capacity across the European space sector for future multi-layer navigation infrastructure.

Improve PNT service accuracy. The in-orbit tests are intended to quantify how LEO geometries, higher dynamics, and more frequent measurement opportunities can improve user performance, including faster convergence and better behavior in challenging environments. These results feed into next-generation PNT concepts that emphasize rapid updates and improved robustness in real-world operating conditions.

Enhance resilience. The program is set up to explore continuity and performance under disruption, including how a LEO layer can complement existing services when conditions degrade. This includes assessing operational concepts that maintain usable PNT in scenarios where signals are impaired or availability is reduced.

Increase security. The demonstrator supports evaluation of features and operational approaches intended to make PNT harder to manipulate, including monitoring and detection concepts and service-level approaches designed to better protect users. This work is aligned with strengthening the trust and assurance profile of European PNT services.

No Astroscale technology is described as being incorporated into Celeste IOD-1 in this overview.

Celeste’s demonstrator phase is being executed by parallel European industrial teams under ESA program management.

Celeste Iod-1 Launch: Esa’s Low Earth Orbit Navigation Demonstrator

The relaunch delivers a robust, protected, and elastic foundation for public-facing services and municipal operations.

A spatial data infrastructure is the organized framework that lets an organization discover, share, manage, and use geospatial information reliably across many teams and systems. In practice, it combines technology, governance, and agreed rules so that maps and location-based services can be published once and reused consistently for planning, service delivery, and day-to-day operations at local, regional, national, and even global levels.

A typical spatial data infrastructure brings together core components such as authoritative data, the technology stack (platforms, storage, and service endpoints), standards for formats and service interfaces, policies and governance for access and stewardship, the people and roles who maintain and use it, and the networks that connect producers and consumers. An example outside Mainz is a national or regional spatial data infrastructure that provides a shared geoportal and data catalog so multiple agencies can publish and consume standardized layers, instead of maintaining separate, incompatible copies.

Developing a spatial data infrastructure commonly follows a phased approach: define goals and stakeholders, inventory and prioritize datasets, establish governance and policies, agree on standards and metadata practices, implement the technical architecture, publish services and catalogs for discovery and access, train users and administrators, and then iterate as requirements and datasets evolve.

The City of Mainz and its municipal data center (Kdz) have teamed with VertiGIS and Esri Germany to overhaul their geospatial infrastructure. The program introduces a certified, cloud-native software-as-a-service environment tailored to current administrative workflows and poised to support upcoming digital initiatives. This approach also aligns with broader infrastructure trends, including cloud adoption, open-data publishing, real-time data feeds, and the growing use of artificial intelligence to enrich data quality and automate routine geospatial workflows.

Platform Stack: ArcGIS Online With VertiGIS Extensions

At the core sits Esri’s ArcGIS Online, a mature cloud service that eliminates on-premises servers for geographic information systems. VertiGIS Studio, VertiGIS FM, and components from the VertiGIS Neo portfolio extend the platform for public-administration work.

<table><thead><tr><th>Component</th><th>Functionality</th><th>Target User/Use Case</th></tr></thead><tbody></tbody><tbody></tbody><tbody><tr><td>VertiGIS Studio</td><td>Builds and configures web mapping applications and user-focused map experiences.</td><td>Administrative teams publishing interactive maps and self-service web apps.</td></tr><tr><td>VertiGIS FM</td><td>Supports asset and infrastructure management workflows tied to spatial context.</td><td>Departments managing facilities, utilities, and municipal infrastructure inventories.</td></tr><tr><td>VertiGIS Neo Components</td><td>Adds specialized solution modules and integration-ready capabilities for domain needs.</td><td>Targeted public-administration solutions that require tailored functions and extensions.</td></tr></tbody></table>

Trust, Compliance, and Scale in the Cloud

Together these layers form an end-to-end architecture that satisfies rigorous information security and data-protection requirements while aligning with regulatory obligations. The result is a flexible, interoperable foundation that can grow with demand and evolving datasets. Interoperability and data sharing are central to this model because they reduce duplication, keep departments aligned on authoritative information, and make it easier to combine datasets across boundaries for faster, better decisions.

In many implementations, common standards support this interoperability, including Ogc specifications for geospatial service interfaces, Iso 19115 for metadata, and Inspire-aligned practices for harmonization and cross-organization exchange. Day-to-day content also spans multiple data types, including vector data (points, lines, and polygons), raster data (gridded imagery and surfaces), attribute data (descriptive fields linked to features), and metadata (documentation that explains provenance, quality, and usage constraints).

When these elements are governed consistently, a spatial data infrastructure improves cross-team coordination, increases operational efficiency, strengthens decision-making with shared context, reduces costs through reuse, and supports transparency by making well-described data easier to find and responsibly publish.

Unified Services for Citizens and Internal WebGIS

The upgrade yields a single, high-performance hub for citizen-centric services and internal WebGIS applications. A cloud-first operating model delivers several operational outcomes:

Replaces fragmented software-as-a-service and managed services

The renewed spatial data infrastructure enables purpose-built apps that simplify daily administrative work. Teams benefit from the following capabilities:

Low-code and no-code application configuration

Mainz’s Spatial Data Infrastructure Relaunch: A Secure, Scalable Geospatial Platform For Public Services

Thinking about mining Bitcoin or other crypto assets? To compete today, you need a high-performing mining rig and a smart setup. We’ve curated the most profitable options so you can choose hardware with strong hashrate, solid efficiency, and a sensible price.

Mining Bitcoin on a typical desktop or laptop is no longer economical, so modern miners rely on purpose-built application-specific integrated circuit hardware instead.

Bitcoin was first mineable on standard computer processors, then miners moved to graphics cards for more throughput. Dedicated application-specific integrated circuit miners ultimately eclipsed graphics cards, delivering far higher hashrate per watt on the sha-256 algorithm.

An application-specific integrated circuit miner is specialized hardware built for one job: performing the sha-256 hashing work needed to compete for Bitcoin blocks. Unlike general-purpose computers or graphics cards, these units focus on hashing efficiency and sustained uptime.

Today’s large operations deploy racks of application-specific integrated circuit miners in climate-controlled facilities with low-cost electricity to maximize uptime and profitability.

If you’re wondering how long it takes to mine 1 Bitcoin, there isn’t a single fixed answer. The timeline depends on your hashrate, current network difficulty, and whether you mine solo or through a pool. With pool participation, you typically earn smaller, more frequent payouts that add up over time rather than waiting to find a full block on your own.

For a practical estimate, use a mining calculator and plug in your miner’s hashrate (for example, a unit rated around 110 terahashes per second), your power cost per kilowatt-hour, and typical pool fees. The calculator output can help you approximate how long it may take to accumulate 1 BTC under your specific assumptions.

Mining 1 BTC per day is generally not feasible for a typical home setup under current network conditions. Hitting that pace usually requires a large fleet of top-tier miners, strong electrical infrastructure, aggressive cooling, and very low energy pricing—more like an industrial operation than a single-machine install.

When you evaluate a Bitcoin miner, keep these essentials in mind:

Hash Rate: This is the number of hashes the hardware computes each second. Higher hashrate usually means a higher price, so balance speed with energy use.

Efficiency: Prioritize joules per terahash. Models such as the Halong Mining Dragonmint T1 have been standouts for squeezing more BTC from each watt of power.

Price: Purchase cost matters, but so do output and electricity. Lower-priced rigs often yield less BTC. The fastest, most efficient miners command a premium—aim for the best value, not simply the lowest sticker or the biggest number.

It’s also smart to factor in reliability and warranty coverage, potential resale value, and real-world availability (including shipping times), since those can affect both your startup timeline and your exit options if you upgrade later.

If you plan to mine at home, be realistic about both initial and ongoing costs. Initial costs typically include the miner itself, a compatible power supply if it’s not bundled, cabling and networking gear, potential electrical work (breakers, outlets, wiring), and basic ventilation or ducting to move hot air out.

Ongoing costs typically include electricity, cooling (fans or air conditioning), routine cleaning and maintenance, potential repairs or replacement parts, and mining pool fees if you’re not mining solo.

Heat and noise are two of the biggest home-mining hurdles. For heat management, prioritize strong ventilation, keep intake air cool, avoid confined spaces, and consider isolating the miner in a garage, shed, or dedicated area with controlled airflow. For noise reduction, choose quieter hardware when possible, place the unit away from living spaces, and consider sound-dampening barriers (without blocking airflow) to cut down on the constant fan noise.

Bitcoin mining also comes with real risks and challenges, including hardware failure, price volatility, potential regulatory changes, rising network difficulty, and the possibility that mining becomes unprofitable if energy costs climb or the market turns.

As for legality, Bitcoin mining is generally legal in the U.S., but rules can vary by state and even by city. Depending on where you live, you may run into zoning constraints, noise limits, utility restrictions or special tariffs, and permitting requirements—so it’s worth checking local regulations before setting up a high-noise, high-draw installation.

If mining at home isn’t a fit, alternatives include joining a mining pool (to smooth payouts), exploring cloud mining (with careful due diligence), or investing indirectly through mining companies rather than running hardware yourself.

With the selection criteria and key makers in mind, explore the leading asic mining hardware below, along with a quick comparison of strengths and trade-offs.

Reviews of Leading Bitcoin Mining Machines

To simplify your decision, we summarized hands-on insights and specs for the most notable miners.

After the runaway success of Bitmain’s Antminer S7 in 2015, the company rolled out the Antminer S19 family.

The lineup includes three models: Antminer T19, Antminer S19, and Antminer S19 Pro.

<table><thead><tr><th>Model</th><th>Hashrate (TH/s)</th><th>Typical Price (USD)</th></tr></thead><tbody></tbody><tbody></tbody><tbody><tr><td>Antminer T19</td><td>About 84</td><td>Around $2,118</td></tr><tr><td>Antminer S19</td><td>Roughly 95</td><td>Not specified</td></tr><tr><td>Antminer S19 Pro</td><td>Near 110</td><td>Approximately $3,769</td></tr></tbody></table>

Antminer S19 Pro: Specs, Noise, and Setup

The flagship of the S19 range reaches up to 110 TH/s, making it one of Bitmain’s most capable sha-256 miners.

Power Supply: Rated at 3,250 W with a tolerance of ±5%.

Noise and Consumption: Expect average operating noise close to 81.4 dB during sustained hashing.

Setup: Using the MinerLink interface, add your mining pool credentials and you’re off. Units auto-resume hashing after power interruptions and connect via Ethernet only.

Temperature: Designed to run between 5–40°C (40–105 Fahrenheit).

Price: Limited chip availability has kept new Antminer S19 Pros in the ~$15,000–$25,000 range, while second-hand units often appear near $13,000. With Antminer S19XP and L7 arriving in 2022 and many commercial miners upgrading, pricing on the S19 series has been easing.

Profitability: Using the same baseline assumptions as for the S19, annual profit can reach roughly $2,000, subject to BTC price and network difficulty.

MicroBT’s responses to Bitmain’s S19 line are the WhatsMiner M30S+ and M30S++.

<table><thead><tr><th>Model</th><th>Hashrate (TH/s)</th><th>Typical Price (USD)</th></tr></thead><tbody></tbody><tbody><tr><td>WhatsMiner M30S+</td><td>Around 100</td><td>Not specified</td></tr><tr><td>WhatsMiner M30S++</td><td>Up to about 112 (±5%)</td><td>Around $3,250</td></tr></tbody></table>

Price and Power: The M30S+ targets around 100 TH/s, placing it near the S19. It’s no longer sold new on MicroBT’s site, so availability is primarily on the secondary market.

Bitcoins/Month (Profitability): Use a Bitcoin mining calculator to estimate returns, factoring in variables like difficulty and pool fees. For example, at $0.12/kWh and a 6.25 BTC block reward, outcomes will hinge on power rates and network conditions.

Power and Noise: The M30S+ draws a bit more power than comparable S19 units and runs near 34 J/TH. Typical noise is about 83 dB.

Temperature: Optimal ambient range is roughly −5 to 35°C (23–95 Fahrenheit), wider than many peers and often helpful for cooler sites.

Price and Power: Priced around $3,250 on MicroBT’s store, the M30S++ offers a compelling alternative to the S19 Pro.

Bitcoins/Month (Profitability): Even with electricity approaching $3,600 annually, its ~112 TH/s capability can net close to $3,611 per year, implying a payback period under 12 months in favorable conditions.

Power and Efficiency: Requires about 3,472 W at the wall and operates near 38 J/TH.

Temperature: Like the M30S+, the recommended range is −5 to 35°C (23–95 Fahrenheit).

Canaan AvalonMiner 1246: Price, Power, and Noise

Canaan, one of the earliest commercial asic makers, introduced the AvalonMiner 1246 in January 2021. Here’s how it compares with rivals in its class.

<table><thead><tr><th>Model</th><th>Hashrate (TH/s)</th><th>Typical Price (USD)</th></tr></thead><tbody><tr><td>AvalonMiner 1246</td><td>Roughly 90</td><td>About $5,500</td></tr></tbody></table>

Price and Power: It’s on par with the Antminer S19 and WhatsMiner M30S, but it often lists higher.

Bitcoins/Month (Profitability): With electricity near the U.S. average of $0.12/kWh, it can run profitably, though recouping the purchase typically takes around two years.

Power and Noise: Draw is about 3,420 W. Efficiency improved markedly versus the AvalonMiner 1146, from ~52 J/TH to ~38 J/TH. Max noise is near 75 dB—quieter than many S19 and M30S setups.

Temperature: Recommended operating conditions span −5 to 35°C (23–95 Fahrenheit).

WhatsMiner M30S++: Best price-to-performance.

Your ideal miner depends on goals, power costs, and budget. Weigh hashrate, efficiency, and availability before you buy. Whichever route you take, best of luck with your Bitcoin mining journey.

2. StormGain: Mobile-Friendly No-Cost Miner

StormGain features an app-based miner that lets users gather small amounts of Bitcoin without purchasing mining hardware.

To get started with the no-cost miner, users typically install the app, create an account, open the mining section, and start an earning session that may need periodic reactivation. The “free” path often comes with limitations, such as slower accumulation, app-use requirements, and withdrawal conditions like minimum thresholds or account checks before funds can be transferred out.

Built-in crypto trading tools for active users.

3. NiceHash: Global Hash Power Marketplace

NiceHash runs a marketplace for buying and selling hash power so users can mine the most profitable algorithms in real time.

NiceHash does not typically center on a permanent free mining bonus, so getting started usually means either funding an account to place a small marketplace order or connecting your own hardware to sell compute through the platform. The “low-risk” approach is to begin with small amounts, confirm payout settings early, and review fees that can apply to orders and withdrawals.

Flexible approach to acquiring or selling compute.

Automatic switching across algorithms for better returns.

Real-time profit and performance tracking.

4. GoMining: Tokenized Cloud Mining Model

GoMining offers tokenized miners, where each digital asset corresponds to physical hardware that produces on-chain rewards.

GoMining is generally not positioned as a free-entry cloud mining option, so users commonly start by choosing a tokenized product, completing the purchase flow, and linking an account or wallet for rewards. Before committing, it helps to review how any ongoing charges are handled and what steps are required to move earned crypto to an external wallet.

Ownership of tokenized mining units tied to real rigs.

Potential passive income paid from mining output.

Blockchain-based transparency for operations.

Multiple entry tiers for different budgets.

5. Hashing24: Industrial Bitcoin Mining Contracts

Hashing24 provides large-scale Bitcoin mining contracts designed for long-term stability and predictable operations.

Hashing24 is typically a paid-contract provider rather than a free mining gateway, so users usually register, select a plan, fund the contract, and configure where payouts should be sent. Contract offers can also come with terms around maintenance charges, payout timing, and minimum withdrawal levels, so it is important to review the full conditions before purchasing.

Clear reporting on performance and payouts.

Growth is driven by easy access and lower financial risk, giving users a path to mine Bitcoin without buying gear or paying for electricity.

Cloud mining typically works as a simple flow: you create an account, choose a plan (or activate a trial/credit), the provider assigns you a share of hash rate on its infrastructure, and your account is credited with rewards based on the plan rules. Traditional mining is different because you are responsible for sourcing equipment, running it continuously, and managing operational decisions, while hosted models shift those operational tasks to the provider and focus you on contract terms and payouts.

Hashing power (often measured in terahashes per second) matters because it directly influences the share of work credited to your account. As a practical rule of thumb, higher hash rate generally increases gross rewards, but the net outcome still depends on fees, reward calculations, and the exact contract formula used by the site.

Profitability is not guaranteed. Results depend on factors such as BTC price changes, the platform’s pricing model, contract duration, fees (including maintenance or service charges), and whether the provider’s reward calculations match what you expect. Free-entry modes often produce very small balances, while paid contracts can end up positive, break-even, or negative depending on market swings and the fine print.

Cloud mining can reduce operational complexity, but it does not remove market risk or platform risk. Treat advertised returns as projections and verify the rules that determine how rewards are calculated and when they can be withdrawn.

Crypto mining sites commonly charge fees in a few categories: contract or plan pricing, ongoing maintenance or service charges, and withdrawal-related costs (including network fees). Fee structure can also reflect the business model: a marketplace-style service can apply order and service fees, app-based earning models can have conditions or conversion costs when moving value out of the app, and contract providers can bundle costs into the plan price or list them separately.

When assessing whether a site is legitimate and safe, focus on verifiable transparency and security practices rather than marketing. Look for clear company and contact details, unambiguous contract rules, an understandable explanation of how rewards are computed, and consistent support responses. Strong account protections—such as two-factor authentication, login alerts, withdrawal confirmations, and encryption—are also important. Common warning signs include guaranteed returns, unclear ownership or location information, hidden fees, pressure to “upgrade” to unlock withdrawals, and confusing terms that make it hard to determine how rewards are actually produced.

Withdrawing earnings usually follows a standard process across most platforms: add or confirm a payout address, meet any minimum threshold, submit a withdrawal request, complete required confirmations, and wait for processing plus the blockchain network confirmation. Platforms may support withdrawals to an external wallet address, transfers to an in-app wallet, or conversion routes that move funds through internal balances before they reach an external address. Limits and requirements can vary, including minimum withdrawal amounts, processing windows, and account verification steps.

When choosing a provider, prioritize practical checks: contract clarity, fee visibility, withdrawal rules, reputation signals you can verify, and the quality of customer support when you test basic questions. It also helps to confirm whether the platform’s “free” offer is a true entry point or a limited promotional path with restrictions that affect how and when you can move funds.

No electricity bills or maintenance overhead.

Onboarding that is friendly to first-time users.

Contracts can provide passive income in BTC.

By 2026, cloud mining has matured into a scalable, contract-led ecosystem that lets users participate in cryptocurrency mining without operating rigs.

Real mining infrastructure powered by renewables.

Structured contracts across multiple tiers.

Free-entry bonuses to start mining instantly.

A referral model for additional passive income.

Meanwhile, StormGain, NiceHash, GoMining, and Hashing24 offer alternative paths to participate in mining activity.

For beginners and experienced users alike, cloud mining remains a practical route to mine Bitcoin, engage in crypto mining, and pursue passive income—without managing physical mining hardware.

How to Find and Join Top Crypto Telegram and WhatsApp Groups?

These hubs share trading signals, market analysis, and long-term ideas. Use the steps below to discover high-quality spaces worth your time.

Social platforms and crypto forums are rich sources. On X (Twitter), Reddit, and dedicated communities, many a group provides public invites and recommendations. You can also find active crypto communities through aggregator directories, Discord servers, Meetup-style event listings, and audio discussion spaces like Clubhouse, especially around major local meetups and conferences.

Use targeted hashtags such as #CryptoTelegramGroup or #CryptoWhatsAppGroup.

Join crypto forums like BitcoinTalk to find curated invite posts.

Follow respected analysts and creators who occasionally share access details.

Protect yourself from scam or fraudulent rooms by checking history, content quality, and feedback from members. Trust and moderation matter.

Before you follow any signal, do basic due diligence: confirm who runs the group, how they communicate risk, and whether their claims can be checked.

Common red flags and scam tactics in WhatsApp crypto communities include:

Guaranteed profits or “no-loss” claims that pressure you to act fast or skip risk management.

DM-only “support” that pushes you toward sending funds, sharing seed phrases, or installing remote-access apps.

Impersonation of admins or “VIP managers” using similar names, copied profile photos, and urgency-driven messages.

Fake screenshots of profits, fabricated “member withdrawals,” or edited track records that can’t be independently verified.

Requests to move funds to “verification wallets,” pay “unlock fees,” or deposit to unknown addresses to “activate signals.”
