Explaining Parker Solar Probe's magnetic puzzle
Write a comment
When NASA's Parker Solar Probe sent back the first observations from its voyage to the Sun, scientists found signs of a wild ocean of currents and waves quite unlike the near-Earth space much closer to our planet. This ocean was spiked with what became known as switchbacks: rapid flips in the Sun's magnetic field that reversed direction like a zig-zagging mountain road.
Scientists think pi Ball Aerospace completes CDR for Roman Space Telescope instrument

Ball Aerospace, partnered with NASA Goddard Space Flight Center, successfully completed the critical design review of the Wide Field Instrument (WFI), which will be the primary science instrument on NASA's Nancy Grace Roman Space Telescope, formerly known as the Wide Field Infrared Survey Telescope (WFIRST).

China and Russia have agreed to join hands in building and running a robotic scientific outpost on the moon or in lunar orbit, according to the China National Space Administration.
The administration said in a statement on Tuesday evening that its head, Zhang Kejian, and his Russian counterpart, Dmitry Rogozin, director-general of State Space Corporation Roscosmos, signed a memorandum of u Perseverance 'SuperCam' begins hunt for past life on Mars

The bundle of instruments known as SuperCam on board the Perseverance Mars rover has collected its first samples in the hunt for past life on the Red Planet, mission scientists said Wednesday.
The return to Earth years from now of the rocks and soil it retrieves "will give scientists the Holy Grail of planetary exploration," Jean-Yves le Gall, president of France's National Centre for Space Hope Probe captures new images of Mars with the Emirates Ultraviolet Spectrometer

The Emirates Mars Mission (EMM), the first interplanetary exploration undertaken by an Arab nation, achieved another major milestone on February 20th, 2021 with the return of the first science images from the Emirates Ultraviolet Spectrometer (EMUS), one of three science instruments on board the Hope probe. The Mohammed bin Rashid Space Centre (MBRSC) released these images to mark one month sinc NASA Targets March 18 for SLS Hot Fire Test

NASA is targeting Thursday, March 18 for the second hot fire of the Space Launch System (SLS) rocket's core stage at NASA's Stennis Space Center near Bay St. Louis, Mississippi.
After performing tests to demonstrate that a recently repaired liquid oxygen pre-valve was working, the team has continued to prepare the core stage, its four RS-25 engines, and the B-2 test stand for the second ho Ideas for future NASA missions searching for extraterrestrial civilizations
Write a comment
A researcher at the Instituto de Astrofísica de Canarias (IAC) is the lead author of a study with proposals for 'technosignatures'—evidence for the use of technology or industrial activity in other parts of the Universe—for future NASA missions. The article, published in the specialized journal Acta Astronautica, contains the initial conclusions of a meeting of experts in the search for intelligent extraterrestrial life, sponsored by the space agency to gather advice about this topic.
In the article, several ideas are presented to search for technosignatures that would indicate the existence of extraterrestrial civilizations, from the most humdrum, such as the presence of industrial pollution in the atmosphere or large swarms of satellites, to hypothetical gigantic space engineering work, such as heat shields to fend off climate change, or Dyson spheres for optimum use of the light from the local star.
Space sustainability and debris physics: The role of reentries
Write a comment
What goes up, nearly always comes back down. When it comes to the objects we send to space, atmospheric reentries are actually a fundamental tool in minimizing the creation of space debris and ensuring a sustainable future in space.
Objects in low-Earth orbit, affected by the 'drag' forces caused by Earth's atmosphere, gradually lower in altitude and then make a rapid and firey descent towards Earth.
Small objects disintegrate as they reenter due to the immense friction and heat created, but parts of larger bodies can reach the ground so should be controlled to land over uninhabited regions.

How do you get power into your lunar base? With a tower of concrete several kilometers high
Write a comment
It sounds like science fiction, but building an enormous tower several kilometers high on the lunar surface may be the best way to harness solar energy for long-term lunar exploration. Such towers would raise solar panels above obstructing geological features on the lunar surface, and expand the surface area available for power generation.
A successful future moon base of any size is going to require two key resources: water and power. Ever since evidence of frozen water ice was discovered in the depths of permanently shadowed craters near the moon's South Pole, the polar region has become NASA's primary target for future moon landings. Water can be used for drinking, of course, and growing plants, but also as rocket fuel or separated out at the molecular level to make breathable oxygen. But while the moon's water is found deep in the crater basins, power generation will likely come from high up, above the crater rims, where 'peaks of eternal light' are known to exist. These peaks almost never experience shadow, and would be ideal locations to place solar cells to power water-extraction activities on the moon.
