India to launch Shukrayaan Venus mission in 2024 after pandemic delays: reports

India plans to launch a new orbiter to Venus in 2024, a year later than planned, according to media reports.

The Shukrayaan orbiter will be the first mission to Venus by the India Space Research Organization (ISRO) and will study the planet for four years, according to SpaceNews, which cited a presentation by an ISRO research scientist at a NASA-chartered committee Nov. 10.

ISRO has been soliciting ideas for instruments for a Venus-based mission since at least 2018, according to its website. At the planetary science committee, ISRO’s T. Maria Antonita presented more information about Shukrayaan during a discussion about NASA’s new 10-year plan for planetary science, SpaceNews reported.

“ISRO was aiming for a mid-2023 launch when it released its call for instruments in 2018, but Antonita told members of the National Academies’ decadal survey planning committee last week that pandemic-related delays have pushed Shukrayaan’s target launch date to December 2024,” SpaceNews stated in a Nov. 19 report. 

A backup launch opportunity is available when Venus and Earth are next aligned in mid-2026, in such a way to minimize spacecraft fuel use during the planetary transit, Antonita added.

Shukrayaan is set to launch on India’s GSLV Mk II rocket, but it may go on the more powerful GSLV Mk III rocket to carry more instruments or fuel, Antonita told the committee. ISRO will make a final decision in the next three to six months.

The spacecraft will carry several instruments to probe the Venusian environment. The flagship instrument will be a synthetic aperture radar to examine the Venusian surface, which is shrouded by thick clouds that make it impossible to glimpse the surface in visible light. An earlier version flew on the Indian Chandrayaan-2 spacecraft now orbiting the moon, Space News reported.

Another instrument will be a Swedish-Indian collaboration known as the Venusian Neutrals Analyzer, which will examine how charged particles from the sun interact with the atmosphere of Venus, according to The Economic Times. An earlier generation of this instrument launched on the Indian Chandrayaan-1 moon mission of 2008-09, studying how the sun’s particles affect a world with a far more tenuous atmosphere.

Shukrayaan will also bring an instrument to Venus to examine the planet’s atmosphere in infrared, ultraviolet and submillimeter wavelengths, Antonita said. Earlier in 2020, scientists announced the possible detection of phosphine —  a life-friendly element —  in Venus’ atmosphere, although many in the science community remain skeptical of the findings. 

In September, the French space agency (CNES) announced it would also fly an instrument on Shukrayaan. The Venus Infrared Atmospheric Gases Linker (VIRAL) is a collaboration with Russian federal space agency Roscosmos. Antonita added that other instruments have been shortlisted and that India plans to fly an instrument from Germany.

The team announced the game was delayed and then ultimately postponed.

University of the Pacific was unable to get their COVID-19 test results back in time for tip-off.

The Thanksgiving holiday is playing a role in this delay.

The game could be rescheduled for a later date.

The Bulldogs host UC Riverside on Monday.

Red coating contaminates SpaceX rockets, delays crew launch

CAPE CANAVERAL, Fla. (AP) — SpaceX’s second astronaut flight is off until mid-November because red lacquer dripped into tiny vent holes in two rocket engines that now must be replaced.

SpaceX and NASA officials announced the discovery of the potentially damaging contamination Wednesday.

The clogged holes were found after the aborted launch of a GPS satellite on Oct. 2. Two of those engines were contaminated with the bright red coating, which protects engine parts during cleaning.

SpaceX later found the same problem with two of the nine booster engines on the rocket that will launch four astronauts to the International Space Station. It will be SpaceX’s second launch of astronauts for NASA after a successful test flight earlier this year.

The engine trouble prompted SpaceX and NASA to bump the launch to Nov. 14, two weeks later than planned.

A company vice president, Hans Koenigsmann, said new procedures are being implemented to the prevent the problem.

“The important part, I think, for us is that we caught it before anything happened,” Koenigsmann told reporters. “Really important for us that we fix it … and make sure that never happens again.”

The clogged vent holes — located in the engine gas generators — are just one-sixteenth of an inch (1.6 millimeters).

On-board computers detected the problem and halted the Oct. 2 countdown in the final few seconds. The contaminated engines could have been badly damaged if they had fired, Koenigsmann said.

The cleaning process is done by an outside company, which was not identified. The problem appears to have cropped up in just the last couple months, he noted, affecting brand new boosters but not the older ones that already have been recycled several times.

SpaceX’s next launch for NASA — a satellite to monitor sea level change — is scheduled for Nov. 10 from California following the replacement of one contaminated engine.
