Washington, April 17: NASA is now targeting Wednesday for the launch of its next planet-hunting mission, the Transiting Exoplanet Survey Satellite, or Tess.
The spacecraft was earlier scheduled to launch on a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station in Florida on Monday (4.02 a.m. on Tuesday, India time).
"Standing down today to conduct additional GNC (guidance, navigation and control) analysis, and teams are now working towards a targeted launch of @NASA_TESS on Wednesday, April 18," SpaceX said in a tweet on Monday .
NASA in a blog post said that the Tess spacecraft is in excellent health, and remains ready for launch.
Tess is NASA's next step in the search for exoplanets, including those that could support life.
Once in orbit, Tess will spend about two years surveying 200,000 of the brightest stars near the Sun to search for planets outside our solar system.
It will find the most promising exoplanets orbiting relatively nearby stars, giving future researchers a rich set of new targets for more comprehensive follow-up studies, including the potential to assess their capacity to harbour life.
With the help of a gravitational assist from the Moon, the spacecraft will settle into a 13.7-day orbit around Earth, NASA said in an earlier statement.
Sixty days after the launch and following tests of its instruments, the satellite will begin its initial two-year mission. Four wide-field cameras will give Tess a field-of-view that covers 85 percent of our entire sky.
Within this vast visual perspective, the sky has been divided into 26 sectors that Tess will observe one by one.
The first year of observations will map the 13 sectors encompassing the southern sky, and the second year will map the 13 sectors of the northern sky.
The spacecraft will be looking for a phenomenon known as a transit, where a planet passes in front of its star, causing a periodic and regular dip in the star's brightness.
NASA's Kepler spacecraft used the same method to spot more than 2,600 confirmed exoplanets, most of them orbiting faint stars 300 to 3,000 light-years away.

HMPV cases: Karnataka CM directs officials to take precautionary measures
Bengaluru (PTI): With two cases of Human Metapneumovirus (HMPV) detected in Karnataka, Chief Minister Siddaramaiah on Monday said he has directed the health and medical education departments to take all the precautionary measures.
"There is information on HMPV or China virus infection in Karnataka. I have instructed the health department to take precautionary measures, I have also spoken to Health Minister Dinesh Gundu Rao. We -- Health and Medical Education departments -- will take all the precautionary measures to control it," Siddaramaiah said.
Briefing reporters here, he said the infections have been detected in two children. "Though it is not a dangerous virus, precautionary measures need to be taken."
"Whatever measures the health department suggests, the government will support all those measures."
The Indian Council of Medical Research has detected two cases of HMPV in Karnataka through routine surveillance for multiple respiratory viral pathogens, the Union health ministry earlier said on Monday.
A three-month-old female infant with a history of bronchopneumonia was diagnosed with HMPV after being admitted to Baptist Hospital in Bengaluru. She has already been discharged, the ministry said.
An eight-month-old male infant with a history of bronchopneumonia tested positive for HMPV on January 3 after being admitted to Baptist Hospital. He is now recovering, it said.
Neither of the patients have any history of international travel.
Meanwhile, the Directorate of Medical Education (DME) here has urged people not to panic as the virus is not as transmissible as Covid-19.
Emphasising that the respiratory virus primarily affects children, causing infections similar to the common cold, the directorate said in a release that hospitals have been instructed to report influenza-like illness (ILI) and severe acute respiratory infection (SARI) cases.
To prevent escalation of the spread of the virus, people are advised to cover mouth and nose while coughing or sneezing, wash hands frequently with soap, avoid public places if symptomatic and close contact with sick persons.
The advisory further urged people not to reuse tissue papers or handkerchiefs, share towels and linen and avoid spitting in public places.
HMPV causes flu-like symptoms including cough, fever, nasal congestion, and shortness of breath. In more severe cases, it can lead to bronchitis or pneumonia, especially in young children, the elderly, and immunocompromised individuals.
The virus spreads through respiratory droplets, close personal contact, and touching surfaces contaminated with the virus followed by touching the mouth, nose, or eyes, it added.
