The launch of NASA's new moon rocket has been pushed back by nearly a month after the Space Launch System failed to complete necessary prelaunch testing, officials said Monday.
With the rocked estimated to lift off sometime between June 6 and June 16, NASA officials said that launching during that window now would be challenging after issues during the SLS's wet dress rehearsal prevente Perseverance at the Delta

Last week's blog talked about the rapid traverse of Perseverance to the Delta. This weeks blog entry will talk about the Delta itself, and why it is something worth rapidly traversing towards!
The prospect of the delta for me is that every day will be full of excitement and could bring anything. Let me explain that a bit further. On a space mission like M2020 you get used an exciting timel Navy conducts historic test of new laser weapon system

The ground-based laser system homed in on the red drone flying by, shooting a high-energy beam invisible to the naked eye. Suddenly, a fiery orange glow flared on the drone, smoke poured from its engine and a parachute opened as the craft tumbled downward, disabled by the laser beam.
The February demonstration marked the first time the U.S. Navy used an all-electric, high-energy laser weap Schedule effects of SLS rollback still uncertain

NASA managers said a rollback of the Space Launch System from its launch pad after three truncated countdown tests will allow them to address issues both at the pad and with the vehicle, but that it was too early to predict what it would do to the schedule for the vehicle’s first launch.

NASA is having a tough time testing the SLS
Monday, 18 April 2022 19:15 Write a comment
NASA's Space Launch System (SLS) has been having some problems getting tested since it rolled out onto launch pad 39B last month. These tests, called wet dress rehearsals, are used to find any problems with loading the propellant and verify that all of the rocket's systems are able to handle it being exposed to cryogenics.
After this most recent attempt on April 14th, it is clear that the SLS isn't ready for flight yet. The problems that the teams have been encountering have led them to make some procedural changes and slight adjustments in operations and software triggers. There are also the leak problems that have shown up that have to be addressed.

Excitement building at Baltimore institute for the James Webb Space Telescope's observations

The image dazzles from a computer screen in the corner of the room: six beams of red-orange light bursting from a luminous Milky Way star.
But the most entrancing part of the picture—among the public's first dispatches from the revolutionary James Webb Space Telescope—lies in the background, where amorphous blobs are really swirling galaxies.
From a desk across the room in Baltimore's Space Telescope Science Institute, astronomical optics scientist Charles LaJoie zooms in, and even more cloudlike spirals appear, once concealed in the reaches of space.
For the scientists at the institute—the hub for all things Webb—the image is there as a reminder of what's to come. When all of Webb's 18 mirror segments are completely aligned, likely before the end of April, astronomers will be able to peer deeper into the cosmos than ever before.
To the astronomers in the room, seeing a background of galaxies from behind the world's most powerful telescope was anticipated. But for the engineers, focused for so long on building the telescope, it was a "wow moment," said Lee Feinberg, Webb's optical telescope element manager for over 20 years.
Satellite payloads soar into space with liftoff of Long March-4C rocket
Monday, 18 April 2022 13:15 Write a comment
An atmospheric environment monitoring satellite was sent into space by the Long March-4C rocket lifting off from the Taiyuan Satellite Launch Center in Shanxi Province, north China early Saturday.
Five atmospheric environment monitoring payloads are carried on the satellite orbiting the Earth, three of which are developed by the Hefei Institutes of Physical Sciences (HFIPS) of the Chinese Academy of Sciences, namely environmental Monitoring Instrument (EMI), Directional Polarization Camera (DPC) and Particle Observation scanning Polarization Meter (POSP), working independently or collectively to monitor the air pollutants at global scale.
With a maximum field of view of 2,600 kilometers, it can cover the entire earth in one day and has a minimum spectral resolution of 0.6 nanometer, enabling EMI to accurately identify unique information in the absorption spectra and then detect and monitor polluted gases such as nitrogen dioxide, sulfur dioxide and formaldehyde.
For DPC and POSP, researchers at HFIPS proposed an innovative detection program called "Crossfire," which combines the spatio-temporal distribution of global atmospheric aerosols and clouds obtained by DPC instrument and the high-precision atmospheric aerosol parameters obtained by the POSP instrument across orbit.
