SpaceX Polaris Dawn crew set for historic private spacewalk
Write a comment
A private crew set out on an audacious orbital expedition Tuesday, journeying deeper into the cosmos than any humans in half a century as they prepare for the first ever spacewalk by non-professional astronauts.
The SpaceX Polaris Dawn mission, led by Shift4 Payments CEO Jared Isaacman, launched early morning from the Kennedy Space Center in Florida and attained its peak altitude of 870 miles (1,400 kilometers) later that day.
"Achievement unlocked—apogee 1,400.7 km," SpaceX said on X Tuesday night.
Billionaire's spacewalk with SpaceX delayed several hours hundreds of miles above Earth

A billionaire will have to wait a little longer to perform the first private spacewalk after SpaceX delayed Thursday's spacewalk by a few hours.
Tech entrepreneur Jared Isaacman and his crew began preparing for the endeavor soon after blasting into orbit on Tuesday for a five-day flight. SpaceX announced the postponement an hour ahead of the planned start of the spacewalk.
No explanation was immediately given, but the company said via X "all systems are looking good.
Billionaire steps out of SpaceX capsule for first private spacewalk hundreds of miles above Earth

A billionaire stepped out for the first private spacewalk Thursday, teaming up with SpaceX on the daring endeavor hundreds of miles above Earth.
Tech entrepreneur Jared Isaacman and his crew waited until their capsule was depressurized before popping open the hatch. Isaacman emerged first, joining a small elite group of spacewalkers who until now had included only professional astronauts from a dozen countries.
"Back at home, we all have a lot of work to do. But from here, it sure looks like a perfect world," said Isaacman.
The commercial spacewalk was the main focus of the five-day flight financed by Isaacman and Elon Musk's company, and the culmination of years of development geared toward settling Mars and other planets.

ICEYE US, a leading provider of radar satellite imaging for Earth monitoring, announced its selection by NASA to supply synthetic aperture radar (SAR) data for the Commercial Smallsat Data Acquisition (CSDA) Program. The agreement is a 5-year fixed-price, indefinite-delivery/indefinite-quantity (IDIQ) contract awarded to multiple companies.
Since 2020, NASA's CSDA program has been acquirin PathFinder Digital Secures US Air Force Contract for Satellite Terminals
Write a comment
PathFinder Digital has been awarded a contract by the United States Air Force to supply its Global Broadcast Service (GBS) satellite terminals. PathFinder's BAT-GBS-85 terminal, a Ka/Ku band, airline-checkable, flyaway system, will be delivered under this contract.
The BAT-GBS-85 has undergone and passed Army Strategic Command (ARSTRAT) Wideband Global Satcom (WGS) testing and is certified High-Speed Plasmonic Modulators Could Boost Space Communication Capabilities
Write a comment
Researchers have successfully achieved data transmission rates of up to 424 Gbit/s across a 53-km free-space optical link using plasmonic modulators, which control optical signals through surface plasmon polaritons. This advancement paves the way for high-speed optical communication links that can transmit data through open air or space.

GPS technology typically provides location accuracy within a few meters, but many of us have experienced moments where it drifts by hundreds of meters or produces entirely wrong coordinates. One contributing factor to this inaccuracy is the number and alignment of satellites in the receiver's line of sight.
GPS satellites are equipped with precise atomic clocks and constantly broadcast the
