Gaganyaan-1 (from Sanskrit: gagana, "celestial" and yāna, "craft, vehicle") will be the first uncrewed test flight of the Gaganyaan programme, with launch tentatively planned for Q4 2025.

The launch was originally scheduled for December 2020, then in December 2021, but it was delayed due to the COVID-19 pandemic. The flight plan was finally ready by April 2022 and the launch is expected to take place in early 2025, after the TV-D1, TV-D2, TV-D3 and TV-D4. It was proposed in April 2022 that the crew module should be depressurized, something kept in the final planning.

The Gaganyaan spacecraft will be launched, with the humanoid robot Vyommitra, by a Human-rated LVM 3 from Satish Dhawan Space Centre and inserted into a 170 x 408 km orbit. The circularisation maneuver will be performed at the third orbit. The landing should follow the same pattern as the TV-D1.

Hybrid-Propellant Rocket Fuel

Rocket engines typically use one of two types of propellant: Solid or liquid. Hybrid-propellant rockets use a combination of these two forms of fuel, and lack some of the disadvantages of both. Their specific impulse is usually between solid-propellant and liquid-propellant rockets. The image shown here is of a 3D-printed grain, designed for a small hybrid rocket engine which would be used to demonstrate rocket combustion. On the left are two helical fuel ports, on the right a de Laval nozzle.

In the News

The first launch attempt of an Australian-made rocket, Gilmour Space Technologies' Eris-1, was made on 29/30 July. The launch vehicle crashed 14 seconds after launch due to insufficient thrust.
The NASA-ISRO Synthetic Aperture Radar satellite launched on 30 July. The first radar imaging that uses dual frequencies, it is a joint project between NASA and ISRO, and believed to cost ~US$1.5 billion, making it one of the most expensive Earth-imaging satellites.

Automaton Rover for Extreme Environments

Automaton Rover for Extreme Environments (AREE) is a NASA Innovative Advanced Concepts project to design a rover that can operate in the environment of Venus, controlled by a wind-powered mechanical computer. Venus' atmosphere is about 90 times denser than Earth's and the surface temperature is at least 462 °C (864 °F), conditions which would prevent a standard electronic computer from operating for any significant period of time. While AREE is being designed for operation on Venus, the rover's design could be re-purposed for use on Mercury, which has a comparably high surface temperature, on Jovian moons Europa or Io, where high radiation makes use of traditional electronics difficult, or on lava flows or highly radioactive areas on Earth.

The project was first proposed in 2015, and funded by the NASA Innovative Advanced Concepts program with a phase-I study in 2016, and a phase-II study from 2017-2018.

Buzz Aldrin's bootprint on the Moon

In July of 1969, Apollo 11 successfully fulfilled John F. Kennedy's goal of a person landing on, and returning from, the moon before the 1970s. Taking off on 16 July, the lunar lander, Eagle, touched down on the evening of the 20th (UTC). Neil Armstrong and Buzz Aldrin exited the lander six hours later, becoming the first men on the moon. The pair stayed on the lunar surface for about 21 hours. This image is actually the second of a pair of images, taken by Aldrin so that the lunar surface's ability to bear weight could be measured.
