You are still wrong.
Refer to previous post giving details of WISE.
We may not have an answer to the Nemesis question until mid-2013. WISE needs to scan the sky twice in order to generate the time-lapsed images astronomers use to detect objects in the outer solar system. The change in location of an object between the time of the first scan and the second tells astronomers about the object’s location and orbit. Then comes the long task of analyzing the data
WISE completed its all-sky survey in 2011, after surveying the entire sky twice at infrared wavelengths. The 16-inch (40-centimeter) telescope ran out of its coolant as expected in 2010, but went on to complete the second sky scan using two of its four infrared channels, which still functioned without coolant. At that time, the goal of the mission extension was to hunt for more near-Earth asteroids via a project called NEOWISE.
NASA has since funded the WISE team to combine all that data, allowing astronomers to study everything from nearby stars to distant galaxies. These next-generation all-sky images, part of a new project called "AllWISE," will be significantly more sensitive than those previously released, and will be publicly available in late 2013.
By scanning the whole sky with the improved AllWISE data, the team will sleuth out the true monsters of the bunch, clusters as big as thousands of times the mass of the Milky Way, assembled even earlier in the history of the universe.
Galaxy clusters from the first half of the universe are hard to find because they are so far away and because not very many had time to assemble by then. What's more, they are especially hard to see using visible-light telescopes: light that left these faraway structures in visible wavelengths has been stretched into longer, infrared wavelengths due to the expansion of space. WISE can hunt some of these rare colossal structures down because it scanned the whole sky in infrared light.
"I had pretty much written off using WISE to find distant galaxy clusters because we had to reduce the telescope diameter to only 16 inches [40 centimeters] to stay within our cost guidelines, so I am thrilled that we can find them after all," said Peter Eisenhardt, the WISE project scientist at NASA's Jet Propulsion Laboratory, Pasadena, Calif. and an author of the new paper. "The longer exposures from AllWISE open the door wide to see the most massive structures forming in the distant universe."
Other projects planned for the enhanced WISE data include the search for nearby, hidden cool stars, including those with masses as low as planets. If a large planet or tiny star does exist close to our solar system, an object some call "Tyche," then WISE's infrared data may reveal it.
Your news link is a few years old. Both the Hydrogen Cooling and funding itself for WISE ran out back in Oct. 2010. WISE was continued for NEOs for a while. The only way that WISE could perform another sky survey is if someone goes up and replaces that Hydrogen cooling.

Reports are reports, there's no point in saying they didn't scan all the sky twice when reports say they did, they are using the data. Including for binary searches.The program is ongoing right now, it didn't end in 2010. There's no point denying it.

January 1999 — NGSS is one of five missions selected for a Phase A study, with an expected selection in late 1999 of two of these five missions for construction and launch, one in 2003 and another in 2004. Mission cost is estimated at $139 million at this time.
March 1999 — WIRE infrared telescope spacecraft fails within hours of reaching orbit.
October 1999 — Winners of MIDEX study are awarded, and NGSS is not selected.
October 2001 — NGSS proposal is re-submitted to NASA as a MIDEX mission.
April 2002 — NGSS proposal is accepted by the NASA Explorer office to proceed as one of four MIDEX programs for a Pre-Phase A study.
December 2002 — NGSS changes its name to Wide-field Infrared Survey Explorer (WISE).
March 2003 — NASA releases a press release announcing WISE has been selected for an Extended Phase-A study, leading to a decision in 2004 on whether to proceed with the development of the mission.

My sources and quotes are obviously useful in re educating you about WISE and it's current status then, seeing as your opinion prior to me posting them was based on something from 2010 and far from accurate. I won't expect your thanks:
