NASA has reported that an engineering model of its DAVINCI descent probe passed a crucial thermal test conducted between late August and early September. To reproduce the conditions expected during the final plunge through Venus’s atmosphere, engineers placed the roughly yoga-ball-sized vessel in a ceramic-lined chamber. They raised the temperature to 465 degrees Celsius over about an hour, matching the rapid heating the probe is expected to experience before reaching the surface. The successful result indicates that the vessel can protect its scientific instruments in one of the most hostile environments explored by spacecraft. DAVINCI is designed to investigate the origin, evolution and present condition of Venus. By examining the planet’s atmosphere in exceptional detail, the mission may help scientists determine whether Earth’s neighbouring planet once had water and conditions suitable for life.

Özet ve soru Prometheus’a aittir. Haberin tamamı: NASA ↗

Beş ifade

  • descent probe: iniş probu
  • thermal test: ısıl dayanıklılık testi
  • ceramic-lined chamber: seramik kaplı test odası
  • rapid heating: hızlı ısınma
  • hostile environment: zorlu ve elverişsiz ortam

YDS mini sorusu

Why was the thermal test an important step for the DAVINCI mission?

  1. It established that the probe could remain permanently operational on the surface without protective materials.
  2. It reproduced the rapid heating expected during descent and showed that the vessel could shield its instruments.
  3. It allowed scientists to measure the composition of Venus’s atmosphere before the spacecraft was launched.
  4. It demonstrated that the planet’s surface temperature is lower than engineers had previously calculated.
  5. It confirmed that liquid water still exists beneath the ceramic walls of the test chamber.
Cevabı ve açıklamasını göster

Doğru cevap: B

Deneyde test kabı, Venüs’e iniş sırasında beklenen hızda yaklaşık 465 dereceye kadar ısıtıldı ve başarılı sonuç, bilimsel araçların korunabileceğini gösterdi. Bu nedenle doğru cevap B’dir.

By surviving a temperature rise that matched the expected Venus descent profile, the engineering vessel demonstrated that it could protect the probe’s instruments from extreme heat.
