First satnav receiver designed to operate in lunar orbit delivered to satellite maker
Friday, 09 June 2023 16:55 Write a comment
The first satnav receiver designed to operate in lunar orbit has been delivered to satellite maker Surrey Satellite Technology Ltd in the UK for integration aboard the Lunar Pathfinder spacecraft.
The complete Navigation payload seen here includes a four helix antenna (left, in the glass box) developed by MDA in Canada, plus the NaviMoon satnav receiver from Swiss company SpacePNT, and the low noise amplifier developed by EECL in the UK, who also undertook the manufacturing and the environmental test campaign for both the satnav receiver and amplifier.
The payload is designed to boost and process faint terrestrial Global Navigation Satellite Signal (GNSS) signals from more than 400 000 km away, harnessing advanced processing and navigation algorithms to fix the spacecraft's position, velocity and timing in lunar orbit in real time.
It is complemented by a lunar Laser Retroreflector Array (LRA) (right), developed by NASA under agreement with ESA, composed of 48 mirrored retro-reflectors that will enable centimeter-scale laser ranging of the spacecraft as it orbits the moon, to authenticate the satnav receiver position fixes during the experiment.
Due to be launched in late 2025, SSTL's Lunar Pathfinder mission will serve as a telecommunications relay satellite for future missions to the moon, to serve assets on both the nearside and farside, orbiting in an 'elliptical lunar frozen orbit' for prolonged coverage over the South Pole—a particular focus for future exploration.
China’s first stackable satellite reaches orbit on solid rocket launch

Imagine you are singing in a choir. You are doing your best, just like everybody else. Suddenly, somebody turns to you and points out that you are not singing the right note. If you are told off in a harsh way, you may feel bad about it, and if this happens too often you might not only feel upset about the choir but might even leave it for good. Eventually, the whole choir could end if everybody just leaves.
It is the duty of the choir conductor (the ESA team head) to be able to address every single situation in the right way,

New spending caps to create challenges for NASA

NASA and congressional officials are still grappling with the implications of a debt-ceiling agreement that enacts spending caps, but acknowledged it likely means the agency will get less money than it requested for 2024.

China is working on a rocket for its moon landing mission, which will send a manned spaceship and a lander to lunar orbit in two separate flights, chief designer of the country's manned space program Zhou Jianping revealed.
The spaceship will send the taikonauts to lunar orbit and dock with the lunar lander. The lander will subsequently carry the taikonauts to the moon's surface. After the Long missions, frequent travel take a toll on astronauts' brains, study shows

As we enter a new era in space travel, a study looking at how the human brain reacts to traveling outside Earth's gravity suggests frequent flyers should wait three years after longer missions to allow the physiological changes in their brains to reset.
Researchers studied brain scans of 30 astronauts from before and after space travel. Their findings, reported in Scientific Reports, revea Capella Space awarded multi-year blanket purchase agreement by NASA

The movement of cosmic ray particles across space, such as electrons and protons, is influenced by the Sun's magnetic field, causing fluctuations in the intensity of galactic cosmic rays (GCRs) reaching Earth in response to the solar cycle. During periods of low solar activity, such as the solar minimum, more GCRs have been observed to reach Earth compared to that for periods of high solar activ Existence of massive first-generation stars with 260 solar masses confirmed

A new study led by Chinese scientists has confirmed the existence of first-generation stars with 260 solar masses for the first time by finding evidence of the existence of pair-instability supernovae (PISNe) which evolved from such massive first stars in the early universe.
Previously, studies had only confirmed the existence of first-generation stars of under 100 solar masses, and thus t
