Episode 84: NASA after the Shuttle. SLS and The Gateway

By Leave a Comment

David Baker

David Baker has been involved with the USA since childhood. First attending a US school in England and then studying in the US under a scholarship program sponsored by Senator Clinton P Anderson. He returned to the USA and worked for NASA on various programs from Gemini to the SpaceShuttle. He was present in mission control in 1970 and witnessed the drama of Apollo 13 first hand.

He joined the British Interplanetary Society in 1965, published his first article in the society’s journal Spaceflight in 1969 and since 2011 has been the editor of that very journal -Spaceflight. To date, he has published a remarkable 110 books by the close of 2018 with a few more in the pipeline for 2019 to mark the fiftieth anniversary of Apollo 11.

(Note – following questions on the veracity of his Phd, David Baker resigned from the BIS as the editor of Spaceflight on 25th March 2021.)

In this episode, we talk about the current status of the space programme in the US and the changing role of NASA.

  • The USA has not been able to launch US astronauts from the USA since the retirement of the Space Shuttle in 2011. NASA found itself in a similar position between 1975 (Apollo Soyuz Test programme) and the first Space Shuttle in 1981.
  • Why NASA dropped the Ares programme and why its replacement, the Space Launch System (SLS) schedule remains unclear. The first SLS mission, uncrewed – Exploration Mission-1 (EM-1) by 2020 and the second crewed mission, Exploration Mission-2 (EM-2) by 2023.
  • The successor to the ISS, the “Gateway” is an international project for a space station in lunar orbit. Only about a third of the size of the ISS and it will have fewer international partners.
  • The gateway is seen by Russia as an American lead programme. Will Russia participate with the gateway or consider a joint Russia/China human spaceflight programme?
  • China/USA cooperation in space has been prohibited ny US law. What prospects that this will change?

Heads of Space Agency Press Conference IAC2018

This is my recording of the Heads of Space Agency press conference 1st October – the first day of IAC2018. This video was not initially intended to be published. But here it is unedit – some may find it of interest.

In Attendance:Left to right

  • Dmitry Loskutov in place of Dmitry Rogozin – (Roscosmos)
  • Hiroshi Yamakawa – (JAXA)
  • Johann-Dietrich Woerner – (ESA)
  • Maggie Aderin-Pocock (Moderator – BBC)
  • Jim Bridenstine – (NASA)
  • K. Sivan – (ISRO)
  • Sylvain Laporte – Canadian Space Agency (not present)
  • Zhang Kejian China National Space Administration (not present)

Some notes

Head of Roscosmos Dmitry Rogozin – prevented by sanctions against Russia to travel to Germany. Replaced by Dmitry Loskutov.

Bridenstein:

  • Experiments on ISS from 103 countries
  • Gateway – Open architecture, a fraction of the size of the ISS. is not in LEO so has no radiation protection from the Van Allen Belts
  • Reduced electromagnetic radiation from Earth. May allow new experiments in astrophysics
  • Multiple trips to lunar surface from the Gateway and hence potential for new science experiments on the surface.
  • Question: Is NASA subsidising SpaceX?  Did not deny it outright at the outset.
  • Nasa’s goal is in establishing a capability, lower cost and enhanced innovation. Ultimately more customers for SpaceX not just Nasa and more service providers – not just SpaceX.
  • My question on when the US law that prohibits US/China collaboration in space will end? 
  • Answer: The law expires and is renewed every year. (Left it open ended really). 
  • Question: Is China space programme is too close to Chinese military? Answer: This is a concern for US government and Nasa will do what its government permits it to do 

Sivan

  • Indi ahs no plans for human missions to the Moon.
  • Regarding India cooperating with China on human spaceflight training, he left it open-ended. I think he was aware of the deal for Modi administration was making with Russia (announced a few days later) but could not say anything at this press conference.

Woerner:

  • ESA Astronauts are learning Chinese. Will fly with China in the future but no date yet.

Episode 75: China -back to the Moon with Chang’ E 4

By Leave a Comment

Ye Quan-ZhiOne mission two spacecraft, China is going back to the Moon with Chang’E 4 mission that I think is the most exciting lunar mission since the 1970s. By the end of 2018, the China National Space Administration (CNSA) will launch Chang’E 4 that will explore the far side of the Moon with a lander and a rover. Since it is on the other side of the Moon, it will be totally out of sight from the Earth. To facilitate communication, a relay satellite will be launched in advance of the lander/rover’s arrival at the Moon.

In addition to engaging private sector companies in China, Chang’E 4 will include a significant level of international collaboration in this mission with payloads from Germany, the Netherlands, Saudi Arabia and Sweden.

Ye Quan-Zhi is a postdoc astronomer who specialises in small bodies in the solar system. Like me, he started off as an amateur astronomer but now uses telescopes with apertures measured in meters rather than inches!  In addition to his research, he writes about space in the Planetary Society’s blog.   As a Chinese national, Quan-Zhi has an interest and an insight into the Chinese Space Programme and in this episode, we spoke about the upcoming Chang’ E 4 mission and the prospects of collaboration between India and China in space.

Change’ E 4 Mission – An overview

Relay Satellite
Named as “Queqiao” or magpie bridge will be launched in May 2018 and placed in the Earth/Moon L2 orbit (also known as a halo orbit) about 60,000km from the Moon (450,000 km from the Earth) in the opposite direction of the Earth. From there it will always have a line of sight of the far side of the Moon and Earth at the same time. Its primary purpose is to act as a relay providing all the communications from the Lander/Rover that will land on the Moon in late 2018 or early 2019.

The two microsatellites from the Netherlands are called “Longjiang-1″ and “Longjiang-2”. The will enter an elliptical lunar orbit and conduct low-frequency radio astronomy experiments.

Lander & Rover
Due for launch in December 2018 or early 2019

The lander and rover are the backup lander and rover to the highly successful 2013 Chang’E 3 mission. Whilst identical in most respects, lessons learnt from Chang’E 3 have been incorporated in modifications to Chang’E 4.

Lander
• Landing Camera (LCAM)
• Terrain Camera (TCAM)
• Low-Frequency Spectrometer (LFS) to investigate radiation burst from the sun and cosmos.
• Lunar Lander Neutrons and Dosimetry (LND), a neutron detector from the University of Kiel University in Germany
• A mini “lunar biosphere” experiment designed by 28 Chinese universities consisting of a 0.8 litre capacity enclosure weighing 3 kilograms. The biosphere contains silkworm eggs, and seeds fro cress and potatoes. Once on the lunar surface, this mini biosphere will maintain a humidity and temperature (1 to 30 degrees centigrade) whilst the lunar surface temperature varies from +100 to -100 degrees centigrade. A HD camera will live stream from the lunar surface the hatching eggs and sprouting seeds during the first two weeks of the mission.

Rover
• Panoramic Camera (PCAM)
• Ground penetrating radar (LPR) to investigate the lunar crust and mantle
• Visible and Near-Infrared Imaging Spectrometer (VNIS), for imaging spectroscopy
• Advanced Small Analyser for Neutrals (ASAN), to investigate how solar particles interacts with the lunar surface.
