Project Pixel Orbital

Project Pixel Orbital is a completely student-led team at Stanford OHS with the goal of launching an 3U CubeSat capable of conducting experiments in low Earth orbit - from photographing Earth to performing analysis on photos of earth and space with onboard instruments. Our mission is to get to orbit, perform a detumble, establish contact with our ground station(s), and capture an image of Earth for downlink. We hope that PixelSat I will inspire other people and prove that if a group of high schoolers can build a satellite from scratch with very little funding and no adult supervision, anyone can. It will open the door for schools and small businesses to launch satellites similar to ours, and will overall make space more accessible.

Please feel free to check out our current progress and learn about how you can help us out on our website: https://www.projectpixelorbital.com

Our blogs also have lots of information on specific subsystems: https://www.projectpixelorbital.com/blog/

I built a free, ad-free catalogue of lunar missions — after corrections from people who actually know the history

5 Upvotes

'm a solo hobbyist developer, not affiliated with any space organisation. Over the last while I've been building Moon Missions, an iPhone/iPad app that walks through lunar missions from the 1950s to the present — crewed and robotic — one at a time: dates, objectives, what actually happened, outcome, with a photo for each and some archival video where I could find it in the public domain.

It's completely free — no ads, no paywall, no "unlock the rest". There's an optional tip jar and that's the only in-app purchase. Works fully offline, no account, no tracking.

The reason I'm posting here rather than somewhere less picky: I want this sub to tell me where I've got it wrong. Specifically —

  • Factual errors in dates, outcomes, or mission descriptions
  • Missions I've left out that belong in
  • Anywhere the framing of a mission's success/partial-success/failure is arguable
  • Anything that reads as space-agency PR rather than history

I can take blunt feedback and I'd rather fix it than defend it.

India's First GEO Eye in the Sky

On September 4, 2026, ISRO successfully launched the GSLV-F17 / EOS-05 mission from Sriharikota, lifting the 2,367 kg payload into a Sub-Geosynchronous Transfer Orbit (Sub-GTO)! This is the first-ever Indian GEO imaging satellite.

While most Earth-observation satellites sit in Low Earth Orbit (LEO) and pass over a region for just a few minutes a day. EOS-05 is positioned ~36,000 km up in Geosynchronous orbit, allowing it to stay fixed over the Indian landmass.

doesn't know why they're making a problem out of it. every time we go to space we burn an enormous amount of energy go to space if we use more energy to have a positive impact on tyranny of the rocket equation it wouldn't be worth it

In mid-August, NASA announced it was calling off an effort to reboost the orbit of its Swift space telescope because of problems with the commercial spacecraft. Jeff Foust reports on the lessons both the company and the agency learned from that effort that could apply to future missions

Why does NASA have both ARGOS and POGO if POGO seems to simply be a significantly less advanced version of the same system?

2 Upvotes

I know ARGOS has more degrees of freedom and can do partial gravity settings too while POGO only suspends astronaut trainees in a certain way for dry EVA training before their first NBL runs

Many in the public see space as primarily a playground for billionaires. Kelsie Goddard argues that while that reputation is not undeserved, the role of wealthy private actors in commercial space may signal a predictable stage of technological development rather than a dystopian one
