elonmuskGoing to try to catch the giant fairing (nosecone) of Falcon 9 as it falls back from space at about eight times the speed of sound. It has onboard thrusters and a guidance system to bring it through the atmosphere intact, then releases a parafoil and our ship, named Mr. Steven, with basically a giant catcher’s mitt welded on, tries to catch it.

Er det ikke lettere å utstyre skjoldet med vinger som gjør at de glideflyr i stedet for å utstyre de med fallskjermer?

Uten at jeg har noen som helst greie på dette synes jeg det høres vanskligere ut. Men det hadde jo vært artig å vite da. Hva med å stille spørsmålet her? :)

Veldig spennende dette! Jeg kan ikke vente til vi får inn mer info! 

 

 

Kan forresten anbefale boken Proxima av Steven Baxter hvis man liker hard sci-fi. Den tar for seg en reise til en planet rundt Proxima Centauri lignende den som faktisk er der i virkeligheten.

I samme slengen nevner jeg også boken Eurora av Kim Stanley Robinson. God fornøyelse :)

Jeg har vært på utkikk etter en graf som illustrerer avstanden fra jorda til de andre planetene i solsystemet som funksjon av tid, helst med faser. Altså en slags oversikt over hvor gode observasjonsforholdene er.

 

Edit: Eventuelt tilsynelatende størrelse (bueminutter) som funksjon av tid.

 

Edit: Jeg fant i hvert fall en tabell over tilsynelatende størrelse, fase og en hel del annet

Life on Mars. Sort of. The true story of six volunteers picked to live on a fake planet.

 

 

https://en.wikipedia.org/wiki/HI-SEAS

HI-SEAS (Hawaii Space Exploration Analog and Simulation) is an analog habitat for human spaceflight to Mars.[1][2][3] HI-SEAS is located in an isolated position on the slopes of the Mauna Loa volcano on the island of Hawaii. The area has Mars-like features and an elevation of approximately 8,200 feet (2,500 m) above sea level. The first HI-SEAS study was in 2013 and NASA's Human Research Program continues to fund and sponsor follow-up studies.[4] The missions are of extended duration from four months to a year.

The purpose of the detailed research studies is to determine what is required to keep a space flight crew happy and healthy during an extended mission to Mars and while living on Mars.[5] Research into food, crew dynamics, behaviors, roles and performance, and other aspects of space flight and a mission on Mars itself is the primary focus. The HI-SEAS researchers also carry out studies on a variety of other topics as part of their daily activities.

One thing under study by NASA is trying to understand crew dynamics such as moralestress management, and how they solve problems as group.[6]

Oppskytning om et par timer av Falcon 9 Block 5
 

The highlight of this flight is the debut of the Block 5 version of the Falcon 9 rocket (which Ars previewed thoroughly last week). SpaceX founder Elon Musk has said this will be the final "substantial" upgrade to the Falcon 9 rocket, optimizing the booster for reuse. The company hopes to be able to fly each Block 5 first stage 10 times before significant refurbishment is required.

 

Ten flights of an individual booster would be hugely significant, as SpaceX has thus far only ever reused each of its Falcon 9 rockets a single time. Additionally, the company hopes to reduce the turnaround time between launches of a Falcon 9 booster, now several months, to a matter of weeks.
