The new colonial movement: In outlining India’s plans for space in 2019, the head of India’s space agency ISRO revealed that they are going to try to complete fourteen launches, more than one per month and a pace that would double that nation’s previous annual record.
For the last two years ISRO has been making this same prediction. They failed to come close in either year. I suspect however that in 2019 they will have better luck.
An evening pause: To signal the end of one year, and the arrival of another.
The January man is here,
The start of each and every year
Along the road forever,
Forever,
Forever.
The image on the right was released during this morning’s first briefing outlining the successful confirmation of New Horizons’ fly-by of Ultima Thule (still on-going as I post this). It, along with other data, has provided an explanation for why the scientists have not detected a significant variation in brightness: Our view is looking down at the object’s poles
Images taken during the spacecraft’s approach — which brought New Horizons to within just 2,200 miles (3,500 kilometers) of Ultima at 12:33 a.m. EST — revealed that the Kuiper Belt object may have a shape similar to a bowling pin, spinning end over end, with dimensions of approximately 20 by 10 miles (32 by 16 kilometers). Another possibility is Ultima could be two objects orbiting each other. Flyby data have already solved one of Ultima’s mysteries, showing that the Kuiper Belt object is spinning like a propeller with the axis pointing approximately toward New Horizons. This explains why, in earlier images taken before Ultima was resolved, its brightness didn’t appear to vary as it rotated. The team has still not determined the rotation period.
They note that the highest resolution images will not arrive until February, though they do expect some good images by tomorrow.
The words above were just announced in the control room for New Horizons. They have confirmation that the spacecraft survived the fly-by of Ultima Thule, and is now ready to begin downloading the data it obtained.
It will take literally a year to get all of that data. They will be holding a first press conference within an hour to outline in greater detail the spacecraft’s status, followed by another briefing at 2 pm Eastern where they will likely release the first images.
In anticipation of receiving data from the fly-by just past midnight last night, the New Horizons team has released the image above, taken 24 hours earlier.
Just over 24 hours before its closest approach to Kuiper Belt object Ultima Thule, the New Horizons spacecraft has sent back the first images that begin to reveal Ultima’s shape. The original images have a pixel size of 6 miles (10 kilometers), not much smaller than Ultima’s estimated size of 20 miles (30 kilometers), so Ultima is only about 3 pixels across (left panel). However, image-sharpening techniques combining multiple images show that it is elongated, perhaps twice as long as it is wide (right panel). This shape roughly matches the outline of Ultima’s shadow that was seen in observations of the object passing in front of a star made from Argentina in 2017 and Senegal in 2018.
This object is definitely strangely shaped.
New Horizons is traveling fast, which is why we won’t get good images until practically the instant the fly-by happens. And the first downloads from that fly-by are due to arrive within the next two hours. Keep your fingers crossed that the spacecraft operated as programmed and captured Ultima Thule in all its weird glory.
One point about the sad state of journalism these days. Numerous media publications posted stories last night celebrating that fly-by, as if they knew it was a success. This is bunk. We won’t know what happened until this morning. To imply we do is the hallmark of fake news.
