    James where?

    You should see two options, in the separation between the first post (yours) in this thread and the first reply - sort by date and sort by votes - the forum defaults to votes.  This may not be an option if you are on a mobile device (I've never logged in on my phone).

    Also how do I get the pics of stuff on the bottom of the post?

    Off topic, but man I kind of hate the whole answer voting thing, this conversation is almost impossible to follow because all the responses have been moved out of place.

    Under the original post on the right you have the option to sort by date (it reverts to chronological order).

    Advanced Camera for Surveys Anomaly on Hubble Space Telescope

    At 8:31 p.m. EST on Feb. 28, the Advanced Camera for Surveys aboard NASA’s Hubble Space Telescope suspended operations after an error was detected as the instrument was performing a routine boot procedure. The error indicated that software inside the camera had not loaded correctly. A team of instrument system engineers, flight software experts and flight operations personnel quickly organized to download and analyze instrument diagnostic information. This team is currently working to identify the root cause and then to construct a recovery plan.

    The telescope continues to operate normally, executing observations with the other three science instruments — the Wide Field Camera 3, the Cosmic Origins Spectrograph and the Space Telescope Imaging Spectrograph — that are all performing nominally. There are no critical observations using the Advanced Camera for Surveys scheduled for the remainder of this week or next week, and the observations that were planned over the next two weeks can be easily rescheduled.

    Originally required to last 15 years, Hubble has now been operating for more than 28 years. The final servicing mission in 2009, expected to extend Hubble’s lifetime an additional five years, has now produced more than nine years of science observations. During that servicing mission, astronauts repaired the Advanced Camera for Surveys, installed in 2002, after its power supply failed in 2007.

  4. I found the hatch opening procedures fascinating.  The professionalism and teamwork of the crew was amazing to watch and showed me a facet of ISS operations I had not seen before.  Watching Oleg Kononenko take a few selfies after the first ingress/egress also brought home the human and historical aspect of this mission.

    Now we wait for the de-orbit and I'm really interested to see how the solar cells hold up during re-entry.

  5. Welcome to the forum, @Cylbruda.

    If you get stuck or need advice about the game don't hesitate to ask either here or in gameplay questions. 

    We also have an excellent community of authors that are happy to assist your writing with good scientific advice if you need it.

    I just googled sci-fi lego and I'm amazed at the creativity involved.  Care to share some pics of your creations?  I'm sure all us rocket nerds will appreciate it.

  6. Welcome to the forum, @Reinhart Mk.1.

    I've been following your Eve thread and find very informative - it has generated a lot of great discussion, ideas and even a duel challenge.  I've also never made it back to orbit from the purple beast so I wish you the best of luck, Mate, I hope you conquer it.  I'm starting to think about giving it a go again myself.

  7. Jeff Bezos spoke at an event last night comparing New Shepard to Virgin Galactic's SpaceShipTwo.

    NEW YORK — As Blue Origin prepares to start flying people on its New Shepard suborbital vehicle, the company’s founder says the altitude the vehicle can reach will put it at an advantage over Virgin Galactic’s SpaceShipTwo.

    In an on-stage interview with SpaceNews during a Wings Club luncheon here Feb. 20, Jeff Bezos reiterated statements made by other Blue Origin executives that the company expects to start flying people on New Shepard later this year.

    “This is the first time that I’ve ever been saying ‘this year,’” he said of those plans. “For a few years I’ve been saying ‘next year.’”

    New Shepard has been going through a flight test program without people on board, including its most recent flight, NS-10, Jan. 23. That test program is “going really well,” he said, citing such milestones as testing of the escape system for the vehicle’s crew capsule. “We’ve tested all the envelope for escape. It’s one of the most complicated things that we’ve done.”

    As Blue Origin prepares to start flying people on New Shepard, Virgin Galactic is also edging closer to commercial flights of its SpaceShipTwo vehicle. The latest test of the suborbital spaceplane, scheduled for Feb. 20 from Mojave Air and Space Port, was postponed because of winds. The company said it will try again Feb. 22.

    Bezos, in the interview, pointed out the altitude difference between the two vehicles. New Shepard has typically exceeded 100 kilometers, an altitude known as the Karman Line, on its test flights. SpaceShipTwo reached a peak altitude of 82.7 kilometers on its most recent test flight Dec. 13, its first above the 50-mile boundary used by U.S. government agencies to award astronaut wings.

    “One of the issues that Virgin Galactic will have to address, eventually, is that they are not flying above the Karman Line, not yet,” Bezos said. “I think one of the things they will have to figure out how to get above the Karman Line.”

    “We’ve always had as our mission that we wanted to fly above the Karman Line, because we didn’t want there to be any asterisks next to your name about whether you’re an astronaut or not,” he continued. “That’s something they’re going to have to address, in my opinion.”

    For those who fly on New Shepard, he said, there’ll be “no asterisks.”

    Bezos emphasized in his remarks that while “we’re in very good shape” in the New Shepard development program, he’s not driven by schedule. “I do keep reminding the team — I’m relentless on this — that it’s not a race,” he said. “I want to fly this year with humans, but we will fly when we’re ready.”

    In an interview that also touched on the company’s New Glenn orbital launch vehicle and the BE-4 engine that will power it, Bezos explained how New Shepard will fit into that overall development plan.

    “The strategic objective of New Shepard is to practice,” he said. “A lot of the subcomponents of New Shepard actually get directly reused on the second stage of New Glenn.” That includes, he noted, a variant of New Shepard’s BE-3 engine that will be used on the second stage of New Glenn.

    “All of those systems will get a tremendous amount of practice with that suborbital mission and will be carried over directly to the upper stage” of New Glenn, he said. “The lessons learned on things like landings and operability and reusability, all those things from the New Shepard program, those also get incorporated into the New Glenn booster.”

    He also tied New Shepard to the early barnstorming era of aviation, where such flights built up expertise to allow the aviation industry to grow in the early 20th century. “That’s going to be our barnstorming,” he said of New Shepard.

    I saw another article on this today showing strange air pressure spikes at 7am and 7pm, every day.

    Thanks, Mate, I was unaware of the phenomenon.  This information comes from Dr Don Banfield of Cornell University in an interview with ARS.

    Quote

    ...scientists have also found something of a mystery in the pressure data on the surface of Mars. Twice a Martian day, at around local 7am and 7pm, there are hiccups in what otherwise should be a smooth rise and fall in surface pressures. Initially, the scientists believed this effect must be caused by something on the lander, but eventually they were able to rule out a cause due to an instrument anomaly or heating source on InSight.

    This feature is repetitive and "slightly strange," said Banfield. It wasn't predicted in any of the global or regional weather models for Mars. Currently, the scientists believe the feature must be some kind of atmospheric wave related to sunrise and sunset on Mars. Perhaps there are downslope air flows moving off steep topography, related to the Sun's movement, that briefly upset the atmospheric changes.

    ... And what does the title means really within the article ?

    I think it's just the tip of the iceberg, discovery wise, considering the results come from just a 2% survey of the sky.  From the same article:
