HELLO WORLD

ROSETTA, ESA'S 'SLEEPING BEAUTY' WAKES UP FROM DEEP SPACE HIBERNATION

ROSETTA WIDE AWAKE AS CHECKUP CONTINUES

Following last week’s wake-up of the Rosetta comet-chaser, ESA’s flight controllers have conducted the first in a series of health checks aimed at assessing how well it came through 31 months of hibernation.



Winners of WAKE UP ROSETTA

We asked you to help us wake up Rosetta from 31 months of deep-space hibernation in a fun video shout-out contest. With over 200 entries and 75 000 votes, you certainly succeeded!

The rules were simple: take out your mobile phone and record a ‘selfie’ of you shouting “Wake up, Rosetta!” But you were far more creative than that…

We were truly impressed by the effort that all of you put into your videos, from getting your pets, friends and families involved and constructing fantastic model Rosetta spacecraft, to storyboarding brilliant stop-motion animations with Lego, and writing entire songs and choreographing dance routines for dozens or even hundreds of passionate Rosetta fans.

Where is Rosetta today?

Next week we take another step towards performing unique science at a comet: Rosetta’s instruments start to get put through their paces in what is known as the “payload commissioning” period of a mission.

ESA’s Rosetta spacecraft has caught a first glimpse of its destination comet since waking up from deep-space hibernation on 20 January.
These two ‘first light’ images were taken on 20 and 21 March by the OSIRIS wide-angle camera and narrow-angle camera, as part of six weeks of activities dedicated to preparing the spacecraft’s science instruments for close-up study of comet 67P/Churyumov–Gerasimenko.

INSTRUMENT COMMISSIONING CONTINUES

We’re now in week four of six dedicated to commissioning Rosetta’s science instruments after the long hibernation period, with the majority now having completed at least a first initial switch on.

Why on earth does it take so long to boot up the system?

Why on earth does it take so long to boot up the system?

There is plenty of time to meticulously and systemmatically boot up the different systems.
Take a look at Where is Rosetta today? . A very good software in 4 dimensions that you can spin around to see how Rosetta is approaching the comet at any point in time.

You get the real truth and not the fucking spin doctors of smear of shit on sole of shoe LKY who can present the moral corrupt and moral bankrupts as moral compasses.
We will get to see those moral compasses hooting and hooting Arseloon and LEE KWA clans chasing that hundreds of billions stolen from us by LKY.
Which will happen the moment LKY become a rotting corpse in days or weeks to come.

Rosetta comet-hunter narrows the gap

Europe's comet-chaser Rosetta has taken a big step towards making its historic rendezvous with a 4km-wide ball of ice and rock in early August.
Controllers confirm the spacecraft conducted a major orbit manoeuvre on Wednesday without incident.
The near-eight-hour thruster burn was designed to slow the satellite's speed relative to Comet 67P/C-G.
More adjustments are required, but the operation was a significant event in ensuring Rosetta meets its target.

Rosetta is about to put on the brakes to ensure that it is on target for comet 67P/Churyumov-Gerasimenko.

This video explains the crucial orbit correction manoeuvres that are required to slow down Rosetta's speed, relative to the comet, from 750 metres per second to just one metre per second between 21 May and 5 August. By then, nine thruster burns (including one test burn in early May) will have reduced the distance between them from one million kms to just under 200 kms.

Last night's orbit correction manoeuvre ran as expected, with nominal completion at 23:00 CEST (21:00 UTC).

The thruster burn got underway as scheduled at 16:21:58 CEST (14:21:58 UTC) and ran for 6hrs:39mins, about 2 minutes less than planned but well within margins. About 190 kg of fuel was used.

The manoeuvre was triggered automatically by a command stack that had been uploaded on Tuesday. Engineers were able to monitor the event in real time via ESA's 35m deep-space antenna at New Norcia, Australia.

The Rosetta flight control team can't say what the precise results were in terms of actual delta-v delivered until Flight Dynamics here at ESOC do a review and orbit determination, which takes a day or so, but if a burn runs for anywhere close to the planned time, then we know it went more or less OK – as it did (see note below).

Burn 3 went well a day or so ago.

What Will Rosetta’s Comet Look Like? How Artists Over The Years Pictured It
Comets are notoriously hard to predict — just ask those people on Comet ISON watch late in 2013. So as Rosetta approaches its cometary target, no one really knows what the comet will look like from up close. Yes, there are pictures of other cometary nuclei (most famously, Halley’s Comet) but this one could look completely different.
Several artists have taken a stab at imagining what Rosetta will see when it gets close to the comet in August, and what Philae will touch on when it reaches the surface in November. You can see their work throughout this article.

This week’s images of comet 67P/Churyumov-Gerasimenko reveal an extraordinarily irregular shape. We had hints of that in last week’s images and in the unscheduled previews that were seen a few days ago, and in that short time it has become clear that this is no ordinary comet. Like its name, it seems that comet 67P/C-G is in two parts.

LAST OF THE FATTIES

With about 4500 km separating Rosetta from comet 67P/C-G, the spacecraft will conduct the last of four FAT – ‘Far Approach Trajectory’ – orbit correction manoeuvres later today.
The manoeuvre aims to further reduce Rosetta’s speed with respect to the comet by about 4.82 m/s, such that Rosetta ends the day with a relative speed of 3.5m/s at a distance of 3500 km.

There should be a lot to learn from the physics involved in the creation of such a peculiar shape.

This prove God throw dice to get that shape.
