Hosted test box that runs drills, seals and bearings in orbit and reports wear
TL;DR Wearloop flies a shared test box on rideshare missions such as ISRO's PSLV orbital platform. Inside, customers' small mechanisms (seals, bearings, drill bits, connectors) run thousands of cycles in real vacuum with simulant dust, while a twin box runs on the ground. Customers pay per slot for the comparison.
Hardware meant for digging or driving on the Moon fails in ways ground tests miss. NASA's review of Apollo surface operations sorted dust trouble into nine categories, including clogged mechanisms, abrasion, overheating and failed seals, and found that ground tests consistently underestimated how bad it would be[1]. Simple fixes helped with traction but did nothing for clogging or wear.
And if you're an Indian team, how do you test a mechanism in space without building a whole satellite? Right now, you mostly can't. ISRO's 2024 orbital platform flight carried 24 payloads, ten of them from non-government groups[2], but each was a full experiment, not a shared slot for a bearing or a seal.
What it does, in regulatory terms: a hosted payload on an authorised rideshare mission. Wearloop holds the IN-SPACe authorisation and the customer supplies a test article.
The seed proposed in-space testing for space mining equipment. A full mining rig can't fly on a rideshare, and you can't reproduce true lunar gravity and soil in low Earth orbit. So I kept the goal and narrowed it to what orbit does test well - long-duration vacuum, thermal cycling and radiation acting on small moving parts, with a sealed cup of lunar simulant where dust matters.
The box holds eight to twelve standard slots. Each slot gives a motor, a load cell, temperature sensors and a small camera. The customer's part runs a scripted duty cycle for weeks, and telemetry comes down daily. An identical box runs in a thermal-vacuum chamber on the ground, so customers find out exactly how far their ground tests drift from flight.
Users are mechanism engineers at rover, lander, satellite and robotic-arm makers. Payers are their programme managers, plus university labs on grants and lubricant or seal suppliers who want flight heritage for a catalogue claim. Slot prices are my assumption to test, because there is no public price list for comparable hosted tests in India.
ISRO's orbital platform now flies startup payloads, including a green thruster and an orbital AI lab from two Indian startups in 2024, alongside two ISRO robotic arms[2]. The 2023 space policy makes IN-SPACe the single window for private space objects and opens resource recovery to private firms[3]. Chandrayaan-4 was approved at ₹2,104.06 Cr in 2024[4].
There is no public figure for hosted mechanism testing in India or globally. The narrow signal is behaviour - a US construction-printing firm flew lunar simulants on a suborbital flight in 2025 just to study how they flow[5], which tells you construction and mining teams will pay for flight data on regolith.
Closer to home, ten non-government payloads on one ISRO flight[2] show Indian demand for flight slots.
A Florida university lab tests space hardware on the ground with its simulants[6]. The construction-printing firm's experiment flew simulants on suborbital flights[5]. In India, ISRO's orbital platform hosts whole payloads, and a sibling idea in this directory offers a ground dust bay. I found no one selling shared in-orbit wear slots with a matched ground twin, and that's the gap.

You're building flight hardware that must not fail before the customers' parts do, which is a slightly awkward thing to promise. Each flight needs IN-SPACe authorisation, launch integration and safety reviews, and the ground twin needs a thermal-vacuum chamber. Revenue only arrives after the first flight, so deposits from slot buyers matter more than any pitch deck.
Yes. Every flight of the test box is a private space activity, so you need authorisation before launch.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't trust AI to clear a part for flight. Qualification calls belong to the customer's engineers, using the full data set.

This is right for a team with flight-hardware experience from ISRO or a satellite startup and the patience to wait two years for a first flight. If you don't have access to launch slots or a test chamber then I'd skip it. Prove first that ten slot buyers will sign letters of intent at a price that covers one flight.
Plan for roughly ₹6–11 Cr, mostly for building the test box, launch costs and a flight-hardware team. Expect about two years before a first flight.
Yes. IN-SPACe authorises every private space object and launch manifest, and you need WPC frequency clearance for the downlink.
Yes, hosted payload services exist in several countries. You would need your own country's space licence, spectrum filings and a launch partner.

Thinking about building Wearloop or something close to it? The make-or-break work is filling enough slots to pay for the first flight, and that's a sales plan I'd be glad to help you build. If you need a hand, you know where to find me. Talk to Yash →
